Benefits of technology

[0014]The description herein of advantages and disadvantages of various features, embodiments, methods, and apparatus disclosed in other publications is in no way intended to limit the present inventio

Problems solved by technology

While performances of recent hardware such as recent CPUs have been updated, their prices have fallen significantly.
Because of differences in features, it is not adequate to share firmware for high-end image processing apparatuses with low-end image processing apparatuses.
As a result, the low-end image processing apparatus uselessly allows dynamic power consumption because the “clock gating” funct

Abstract

An image processing apparatus includes: a multi-core CPU having multiple cores; a selector that selects either a first mode or a second mode with respect to allocation of control tasks to the cores of the multi-core CPU; and an allocator that allocates control tasks to the cores of the multi-core CPU by the symmetric multiprocessing technology when the first mode is selected by the selector, and that allocates control tasks to the cores of the multi-core CPU by the asymmetric multiprocessing technology when the second mode is selected by the selector.

Description

[0001]This application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2015-165387 filed on Aug. 25, 2015, the entire disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]The present invention relates to: an image processing apparatus such as a multifunctional machine having multiple functions, e.g., printer function, facsimile function, and scanner function; a control task allocation method for the image processing apparatus; and a recording medium.[0004]Description of the Related Art[0005]The following description sets forth the inventor's knowledge of related art and problems therein and should not be construed as an admission of knowledge in the prior art.[0006]While performances of recent hardware such as recent CPUs have been updated, their prices have fallen significantly. It is a recent trend to reduce the costs of hardware development by sharing hardware resources for hig...
